IMPROVED DEYICB FOR CONTROLLING- HORSES.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all whom it may concern.-

Be it known that I, NORMAN P. SLADE, of Franklin Grove,in the county of Lee, and State of Illinois, have invented a newtand useful Device for Controlling, Checking, or Stopping Horses while attached to the horsepower-of threshing or other machinery; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had Yto the accompanying drawings, which form a part of this specification.

Figure l is a perspective view, showing the combination and arrangement of the several parts when in working order.

Figure 2 represents the upright revolving shaft of the device detached from the stool, with the quadra# pled check-lever attached to its upper end, and the spool or capstan (to which the check-lines are attached) connected with its lower end, which gives aperfeet connection at a-ll ltimes between the driver and the teams. Figure 3 is an enlarged view of the spool or capstan, .showing on its upper surface the slotted holes in which the checklines are fastened by means of knots, and at its lower periphery the pawl and ratchet, which secure safety, while working about the cylinder, by preventing the check-lines from uuwinding, and allowing the'teanis to start incidentally.

Figure 4 represents the revolving seat detached from the upright spindle, which serves to keep the seat in position by means of a pin passing through the upright shaft and working in the said annular groove.

To enable those who are skilled in manufacture, the better to understand my invention, I will proceed to describe it more fully, as follows:

In tig. 1, A represents a table or platform, attached to the horse-power in any convenientand secure way.-

D, the drivers seat, which revolves with or independent of the stool or frame B, in a manner similar to a revolving desk-stool.

L replesents the ordinary lever, to which the horses shaft, (in which itA tnrns,) and shows an annular groove in the lower extremity ofthe stoolare attached with a pulley, p, iu its outer end, and small.

Al, the check-line, which` leads from the bridle-bits has its bearing in the crossing of the crossbars t, and

its upper end revolves in the centre of the stool or frame B.

Above the top of the frame B, the shaft C is square, and to this square end is attached the quadruple checklever l (l cl d, the said lever having.,r four ends, at equal distances apart, so that one of them will always be in convenient reach of the driver; and to the lower end of i the shaft O is attached the spool or capstan f. The said spool or capstan being made of iron, or `any suitable material, has in its upper surface holes e, with short slots extending from them, in a line parallel with the periphery ofthe spool or -capstan, as shown` in iig. 3, and the check-lines are attached to the said spool or capstan in the same manner in which violinstrings are attached-to the tail-piece cfa violin.

.Onthe lower periphery ofthe spool 0r capstanf, is a ratchet, in or with which th'e pawl r engages, (also shown in tig. 8.) The said pawl serves to prevent the check-lines l from slacking (in the absence ofthe driver,) by holding the spool or capstan ffrom revolving backward, thus securing safety to any one who may be at work about the cylinder, (fixing teeth or other parts,) by preventngthe horses from start-ing up incidentally, as they are very apt to do, endangering life and limb.

In iig. 3, the holes e, with their slots, together with the pawl and ratchet, (which are onanenlarged scale,) have already been described, setting forth their uses and design clearly. v

In iig. 4, D is the drivers seat, to which is attached an iron spindle or shaft, x. In the lower end of the spindle is an annular groove, shown at a. This spindle or shaft a: rests in a hole or socket in the upper end of the upright check-shaft C, and a pin o, passes through the shaft G and the annular groove in the spindle or shaft and secures the seat lirmly in po sition, and allows it to revolve freely, at the option of the driver. The seat D is suiciently high above'the stool or frame B, to allow Athe check-lever d d d d to work freely between them, and its four ends project far enough beyond the edge of the seat to enable the driver to grasp them readily.

The stool or frame B, together with the check-shaft G, check-lever (l d el d, spool or copstnn f, and seat D, inn-y be readily removed from the plattform A, (for lo-,nling or transportntion-purposes,) by simply turning the buttons or clasps c, so :is to release the cross-bars i. The advantages of my invention :1re obvious: First, the driver is enabled, with it, to check the speed ot his teams :it his option, and, when he chooses, can stop them without leaving his sent or speaking to them; secondly, by n series of knots in the check-'lines I, the teznns can all be held even, and mode tov draw alike in :i great measure; the driver is furnished with zi good and comfortable sent, in cose of accident he con stop his teams from pulling instantly, thereby, mamy times, saving life and last, though not least, while or the breaking of limbs, and further damage to machinery.

Having,T thus described my invention, Wha-t I claim as new, and desire to secure by Letters Patent of the United States, is

The combination of the check-cord l, or its equivalent, revolving shaft G, levers l el d (Z, and capstan f, with zt horse-power, A, for the purpose of checking and controlling the horses attached to said power, at the option of the drivel', substantially :is shown and described.
